IAAI CFI EXAM QUESTIONS AND CORRECT
DETAILED ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A+
Combustible Liquid - ans -A liquid with a flash point ABOVE 100F
12.5 - ans -If the current flowing out from an electrical panel is 12.5 amps, and it
then flows through an electrical load of 1500 watts, what is the amperage of the
remaining current flow of the return circuit?
Government Institute - ans -NFPA is not this type of institute
Guide - ans -NFPA 921 is this type of document
Guidelines - ans -The information presented in NFPA 921 establishes WHAT?
Hazards - ans -Biological, chemical, physical, and radiological are examples of this
concept that fire investigators should be aware of when investigating a fire scene
Header - ans -The first cutting unit on a combine
Heat flux - ans -The measure of the rate of heat transfer to a surface
Heat of Combustion - ans -The amount of heat released during complete
combustion, which is considered a constant for a specific fuel
(Generally considered a material property and therefore a constant for a specific
fuel)
Heat of Ignition - ans -The heat energy that brings about ignition
(divided into two parts: (a) equipment involved in ignition and (b) form of heat of
ignition)
Heat Release Rate - ans -The fire characteristic that most affects fire growth
during the pre-flashover phase of a fire
,Heat transfer - ans -The transport of heat energy from one point to another point,
caused by temperature difference between those points
Heat transfer - ans -The fire phenomenon responsible for much of the physical
evidence used by fire investigators
High-Order Damage - ans -The shattering type of explosion damage
H.I.N. - ans -The type of number an investigator should look for during a boat fire
investigation
Hot Surfaces - ans -This vehicle component will NOT usually ignite gasoline
Human Body Fat - ans -Component of the human body that will act as a fuel and
sustain a flame
Hypergolic Material - ans -Any substance that will spontaneously ignite or explode
upon exposure to an oxidizer.
Hypergolic Materials - ans -Materials that can react with each other
Ignitable Liquid - ans -A type of material that, when trapped in a concrete floor,
can be recovered by using lime, diatomaceous earth, or non-self-rising flour.
Ignition by Electrical Energy - ans -Ignition that involves transferring sufficient
heat to a fuel by passage of electrical current to ignite material that is closeby
Ignition Temperature - ans -The minimum temperature needed to heat a fuel so
as to ignite and begin self-sustained combustion
Incandescent Light Bulbs - ans -An item that tends to "pull" toward the heat
source
(*if over 25 watts)
, Incendiary Fire - ans -A category of fire that is strongly indicated by the
confirmation of multiple fires
Incendiary Fire - ans -A category of fire that is associated with multiple fires and
trailers
Incident Scene Commander - ans -This person can grant permission for a fire
investigator to enter a scene before the fire is completely extinguished
Inductive Reasoning - ans -The reasoning process of moving from specific
observation to broader generalizations
(*Induction is to "increase"
*Develop hypothesis ("induce")
*More uncertain than deduction
*Based on empirical data, training, and experience)
Interested Party - ans -Any person, entity, or organization with obligations or
whose rights or interest might be affected by the investigation of a specific
incident
Interviews - ans -(1) Trust, (2) Caution, and (3) Distrust are three types of what?
Inverted Cone Pattern - ans -This fire pattern is often caused by a natural gas leak
Inverted Cone Patterns - ans -Fire patterns commonly created when a vertical
flame plume does not reach the ceiling
Team Leader Committee - ans -In what group is one representative selected from
each investigative party?
Irregular Pattern - ans -A certain pattern that is not necessarily an indicator of the
presence of an ignitable liquid
Job Performance Requirement - ans -A professional description that (1) describes
the specific job task, (2) lists items necessary to complete the task, and (3)
describes measurable outcomes and evaluations for the task
